⸻ uPVC Aluminium Windows

KF 520

Our Internorm KF 520 uPVC-aluminium windows are available from Wolf Line throughout Scotland and the North of England. These windows feature a modern, minimalist design, with slim frames and expansive glass surfaces that maximise natural light.
Equipped with high-performance, triple-glazed heat-insulating glass, they offer outstanding energy efficiency by preventing heat loss and keeping cold air outside. The KF 520 windows also include a triple gasket seal, enhancing their thermal insulation and weather resistance for superior performance in all conditions.
